Syntax
path-failure { s11 | s12 | s1u | s4 | s4u | s5 | s5u } ( local-purge | signal-peer }
default path-failure { s11 | s12 | s1u | s4 | s4u | s5 | s5u }
default
Returns the command to the default setting of “local purge” for the selected interface.
{ s11 | s12 | s1u | s4 | s4u | s5 | s5u }
Specifies the interface to which the action will be applied.
s11
: Applies the path failure action to the S11 interface between the S-GW and the MME.
s12
: Applies the path failure action to the S12 interface between the S-GW and the RNC.
s1u
: Applies the path failure action to the S1-U interface between the S-GW and the eNodeB.
s4
: Applies the path failure action to the S4 control plane interface between the S-GW and the SGSN.
s4u
: Applies the path failure action to the S4-U user plane interface between the S-GW and the SGSN.
s5
: Applies the path failure action to the S5 interface between the S-GW and the P-GW.
s5u
: Applies the path failure action to the S5-U user plane interface between the S-GW and the P-GW.
{ local-purge | signal-peer }
Specifies the action to apply to the selected interface.
local-purge
: The S-GW clears the affected bearer (or PDN if path failure is received on a default bearer)
locally without informing the peer. This is the default action for all interface.
signal-peer
: The S-GW initiates control signalling towards the peer MME and P-GW. When signalling:
For a bearer deletion, the S-GW sends a Delete-Bearer-Command message to the P-GW and a Delete-
Bearer-Request (with EBI) message to the MME.
For PDN deletion, the S-GW sends a Delete-Session-Request message to the P-GW and a Delete-
Bearer-Request (with LBI) message to the MME.
The S-GW will not wait for Delete replies from the peer. The request will be sent only once and local
resources will be reset.
